Interface HttpClientMetrics<R,W,S,E,T>

The http client metrics SPI that Vert.x will use to call when http client events occur.

The thread model for the http server metrics depends on the actual context thats started the server.

Event loop context

Unless specified otherwise, all the methods on this object including the methods inherited from the super interfaces are invoked
with the thread of the http client and therefore are the same than the
VertxMetricscreateMetrics method that created and returned
this metrics object.

Worker context

Unless specified otherwise, all the methods on this object including the methods inherited from the super interfaces are invoked
with a worker thread.
